Abstract

Variance of impedance of the current path of each capacitor element is suppressed. A capacitor (100) is provided with a plurality of capacitor elements (10) each of which has electrodes on facing two end surfaces (10a, 10b), respectively. The capacitor elements are arranged in a row so that the end surfaces (10a, 10b) are positioned on the same flat surfaces, respectively. On the same side surface (10c) of each capacitor element (10), a positive electrode bus bar (30a) and a negative electrode bus bar (30b) are arranged along the arrangement direction (x direction) of the capacitor elements (10). The positive electrode bus bar (30a) and the negative electrode bus bar (30b) have external connecting terminals (34a, 34b) for electrically connecting electrode connecting sections (32a, 32b) connected to each electrode and the electrodes to the external. Furthermore, on the positive electrode bus bar (30a), a slit for detouring a current is formed along the arrangement direction (x direction) from the side of the external connecting terminal (34a).
